We did our open water padi with crystal dive and it was fantastic. A four day course with four day free private accommodation. The site is on the beach so no need to walk far with the heavy bags either. Our instructor Tom was really helpful and friendly. Would definitely recommend.

Finished my Openwater with Crystal and had Ana amazing time. Melanie was such a great teacher and not only taught us everything but was pointing out interesting and cool fish whilst diving in the ocean. Even fought off a triggerfish for the group.Also a huge thank you to Mathijs would lead me to complete my Advanced course. An amazing time diving in some very unique and beautiful dive sites.

My boyfriend and I completed our open water diving certification last month and it was truly one of the most amazing experiences I have ever had. At first I was unsure whether I should get my diving license because I can't swim particularly well. However, after speaking to our instructor George, I felt very motivated and encouraged to give it a try. George was always helpful and supportive when I had questions or concerns. Thanks to its clear communication underwater, I always felt safe. He really is an excellent diving instructor and puts a lot of emphasis on us learning the important skills correctly. Celine, who is currently doing her divemaster, was always there to support and help us. Thanks to George and Celine we had an unforgettable experience. I can highly recommend the diving school and especially diving instructor George!

I fell in love with diving here. Originally my intention was just to take the Open water course but enjoyed it SO much that I ended up taking the Advanced Open water, Nitrox and Wreck specialty followed by the Rescue course.I felt super comfortable breathing under water from the get go. Even when I struggled a bit with one skill, our instructor Bo helped me build the confidence to do it successfully.He is super engaging, easy to understand and is a lot of fun - a top notch educator.Class ratios were super safe with 4 students to 1 master instructor and 1 assistant.It’s worth mentioning that Crystals Open water course is over 4 days versus 2.5 at some other schools which was a deciding factor.I’m stoked to travel all over Southeast Asia and dive some of the world’s best sites now equipped with PADI specialty certifications!If you’re looking for a life changing experience look no further than Bo at Crystal Dive!

The open water course at Crystal Dive is definitely recommended. Had a great four days. Mathijs was our instructor and we couldn't have asked for a better instructor! Mathijs takes all the time to give you a nice, familiar and confident feeling under water! Crystal Dive's service is also top notch. We liked the open water course so much that we immediately opted to take the advanced course

I completed both my open water and advanced open water at Crystal. My instructor Maria was incredible. She was so supportive and encouraging throughout the course and had so much expertise to offer about diving on Koh Tao. Can’t recommend her or Crystal enough. Such an exciting experience!

We just completed our open water dive with crystal dive with Alex our divemaster. We did the learning in advance and the course was super efficient. Alex was very patient, encouraging and supportive. I struggled with some aspects and he always kept me calm and reexplained the skill till I got it!We went to 4 sites and saw some incredible sites. Alex explained all the fish we saw afterwards and it was awesome!

I completed my Advanced open water, Peak Performance Buoyancy speciality and my Rescue diver course with Crystal Dive & I can highly recommend this diving school. My instructor Maria was so patient, improving my confidence as a scuba diver & ensuring I always had fun in the underwater world : ). I was even lucky enough to have 1:1 on both courses, making it super easy to learn new skills.I had a brilliant time diving with Crystal and cannot wait to come back in the near future 😊😊

Crystal is an awesome diving school! The crew here is the best, both very fun to go diving (or have some drinks 🙂 ) with, while at the same time they adhere to the highest teaching and safety standards at all time, they really know what they are doing! Thanks Alex for teaching the open water course, I will be back for my advanced soon!!
